Key Takeaways:
Flexeril isn’t a controlled substance, but misuse is possible — Although cyclobenzaprine (Flexeril) isn’t classified like opioids or benzodiazepines, it can still be misused, lead to dependence, and contribute to psychological addiction if taken longer than prescribed or in higher doses.
It’s intended for short‑term use and affects the CNS — Flexeril is prescribed for acute muscle spasms and works by impacting the central nervous system. Its sedative effects make it useful for short periods (usually under three weeks).
Dependence vs. addiction — Physical dependence (tolerance and withdrawal symptoms) can happen with prolonged use, while true addiction involves compulsive use despite negative consequences.
Risks increase with mixing substances — Using Flexeril with alcohol, opioids, or other CNS depressants greatly raises the chance of dangerous effects, including overdose and respiratory depression.
Question:
Is Flexeril addictive?
Answer:
Flexeril (cyclobenzaprine) is a commonly prescribed muscle relaxant used to treat acute muscle spasms and associated pain. While it is not a controlled substance like opioids or benzodiazepines, it still carries potential risks when misused. Flexeril works by affecting the central nervous system and is typically intended for short‑term use (often less than three weeks); longer use increases the chance of side effects and misuse.
The medication’s sedative properties can make it attractive for those seeking relaxation, which may lead some individuals to take higher doses or continue taking it beyond medical guidance. Over time, misuse can lead to physical dependence, where the body adapts and withdrawal symptoms may occur if use stops abruptly, and even psychological addiction, characterized by compulsive behavior and continued use despite negative consequences.
A key distinction exists between dependence (tolerance and withdrawal) and true addiction (persistent misuse and harmful patterns). Importantly, combining Flexeril with alcohol, opioids, or other central nervous system depressants significantly raises the risk of severe sedation, respiratory depression, and potential overdose. Awareness of proper use, potential dependence, and the heightened danger of polydrug interactions is essential for safety.
Introduction to Flexeril
Muscle spasms and acute pain often send people searching for relief, and Flexeril—also known as cyclobenzaprine—is a common prescription doctors use to treat these issues.
The answer is nuanced. Although Flexeril is not classified as an opioid or a controlled substance by the DEA, it does pose risks for misuse, dependence, and psychological addiction. Understanding these risks is crucial for anyone prescribed Flexeril or concerned about a loved one.
This guide will explore what Flexeril is, how it works, its potential for misuse, and the key differences between dependence and addiction. If you’re concerned about muscle relaxant misuse, learn about prescription drug addiction and how to seek help.
What Is Flexeril and How Does It Work?
Flexeril is a muscle relaxant most often prescribed for short-term relief of muscle spasms tied to acute, painful musculoskeletal conditions. These are medical conditions diagnosed and managed by healthcare professionals. Chemically, it’s related to tricyclic antidepressants and works by affecting the central nervous system (CNS).
Unlike medications that directly target muscles, Flexeril blocks pain signals sent to the brain, helping relax muscles and reduce spasms. Most often, it’s prescribed along with rest and physical therapy. Healthcare providers carefully monitor prescription medications like Flexeril to ensure safe and effective use.
Because of its sedative properties, Flexeril is almost always used for brief periods—typically less than three weeks. There’s little evidence supporting long-term use, and side effect risks increase the longer it’s taken.
Common Side Effects
Even as prescribed, Flexeril can cause side effects, including:
- Drowsiness or fatigue
- Dry mouth
- Dizziness
- Blurred vision
- Nausea
These effects show how much the medication can impact brain chemistry and why close monitoring is essential.
Is Flexeril Addictive? The Medical Reality
So, is Flexeril addictive? While Flexeril isn’t a federally controlled substance, that doesn’t mean it’s risk-free. Many people mistakenly believe lack of regulation means a drug is safe from addiction, but the potential for misuse still exists. Misused prescription drugs, including Flexeril, can contribute to drug abuse and may require intervention from medical professionals to prevent serious health consequences. For more information on the risks of prescription drug abuse, consult resources from the National Institute on Drug Abuse.
The Potential for Misuse
Flexeril’s relaxing, mildly sedating effects can make it attractive to those struggling with stress or looking for a “high.” Some take more than prescribed to chase a sense of calm or euphoria.
Risks escalate when Flexeril is combined with other substances, such as or opioids. Combining Flexeril with other prescription drugs, over-the-counter medicines, or prescription painkillers can significantly increase the risk of severe health complications. Dangerous combinations like these can result in overdose, severe sedation, and respiratory depression. For more, see our article about the dangers of mixing substances.
Dependence vs. Addiction
Understanding the difference is key:
Physical Dependence develops as your body adapts to the medication, leading to withdrawal if you stop suddenly. Drug dependence can develop from a misused prescription, and may result in withdrawal symptoms when stopping the medication. Long-term Flexeril use may result in tolerance, requiring higher doses for the same effect.
Addiction (Substance Use Disorder) involves compulsive use despite consequences—often to cope with stress, escape reality, or enhance the effects of other drugs. Learn more in our addiction resource center.
While Flexeril may not create cravings as strongly as drugs like heroin, ongoing misuse can lead to psychological dependence, drug dependence, and a lasting substance use disorder. Misused prescription medications increase the risk of developing dependence and experiencing withdrawal symptoms.

Signs of Flexeril Misuse and Addiction
Because Flexeril is a legitimate prescription, misuse can go unnoticed. The negative consequences of Flexeril misuse can be especially severe for certain groups, particularly those who are young adults or have a history of substance use. If you or a loved one show these signs, consider seeking help from our team:
Behavioral Signs
- Visiting multiple doctors to obtain Flexeril (“doctor shopping”)
- Running out of medication before the next refill
- Neglecting hobbies, responsibilities, or relationships
- Secrecy or defensiveness about medication use
- Using Flexeril without a prescription
Physical Signs
- Slurred speech or confusion
- Loss of coordination
- Rapid or abnormal heart rate
- Excessive drowsiness or trouble staying awake
- Flushed skin and dilated pupils
If you recognize these signs, read about how to help someone with addiction.
The Dangers of Mixing Flexeril
One of the most serious dangers is polydrug use. Because Flexeril depresses the CNS, adding depressants like alcohol or opioids greatly increases risk. Learn more about the risks of mixing muscle relaxants.
- Alcohol and Flexeril: Both slow brain activity, and together can dangerously sedate the body or suppress breathing.
- Opioids and Flexeril: Common among patients with chronic pain but extremely risky due to respiratory depression and increased overdose danger.
For more about this risk, see our guide on opioid and prescription drug interactions.
Withdrawal Symptoms and Detox
Quitting Flexeril suddenly can trigger “Flexeril discontinuation syndrome.” Symptoms include:
- Nausea and vomiting
- Headaches
- Fatigue
- Muscle aches
- Anxiety and trouble sleeping
Medical detox, offered at Footprints to Recovery’s detox programs, helps you withdraw safely with professional oversight.
